As a backup power source ?

Post by Nagaman » Fri, 29 Nov 2019, 11:57

Apparently the Leaf can do house power backup so is that something to look forward to with Tesla?.
We have have serious power disruptions approximately twice a year and never get so much as an offer of compensation for lost food resulting.
Not happy.

Tesla owners practically live in their cars, so they're killing two birds with one stone :D

Leafs have chademo which is bi directional. Teslas don't have chademo so I wouldn't expect it any time soon. Also Elon Musk said a few years back that teslas won't have car to grid. I'd guess the argument is he wants to sell you a power wall

As a rule no. CCS protocol doesn't include VTH or VTG capability right now, but it will be included in the future.

For emergency power, I wanted to put a 1000w inverter directly of the model3 battery. I was thinking about putting a 120amp x 40cm (with 100amp fuse) wire to a surface mounted 100amp anderson plug located in the frunk. I could then put the car in neutral and run the inverter.

From my research:

I believe the DC to DC inverter in the model 3 should be able to supply at least 1.5kw (to 12v battery) safely.

I did the same for my older 2008 prius and it worked like a charm, could keep the fridge + other essentials going in an emergency.

It seems silly that I have a massive 50kw battery that I cannot use for emergency power.

Can anyone see any flaws in my approach????

No. Been done with the Kona Electric already. Having a selectable Utility Mode makes it workable...
